|repeated daily exposure, 21.5 h/day for 25 months
|Circularly polarized. 2,45 GHz was chosen so that each rat would have approximately the same size to wavelength ratio as a human being exposed to 1 mW/cm² 450 MHz RF field.
|Packets per second
Modulation characteristics of the pulses: 8 groups per second, fifty 10 µs wide pulses per group with a repetition rate of 800 pps. The period was 125 ms; with pulse onsets separated by 1.25 ms interval.
|Animals housed in plastic cages
|Exposure facility consisted of two rooms consisting of 100 waveguides. Each alcove housed 20 waveguides mounted on four horizontal shelves, 5 waveguides per shelf. The exposure and sham exposure waveguides were randomly arranged. Each exposure room was equipped with two 2.45 GHz pulsed microwave sources
The results showed no biologically significant effects on general health, serum chemistry, hematological profiles, longevity, cause of death, and lesions associated with aging and benign neoplasia. Statistically significant effects were found in corticosterone levels and immunological parameters at 13 months exposure (the results could not be confirmed in a follow-up study). In exposed young rats O2 consumption and CO2 production were lower (the effects were not observed in mature rats). The results of an excess of primary malignancies in exposed rats is provocative.
